typescript declare：`export function` 和 `export type .. lambda` 有什么区别？

Question

导出有什么区别：

index.d.ts

declare module '@my/customs'{
    export function ModuleFactory(environment:any): any
}

和

declare module '@my/customs'{
     export type ModuleFactory = (environment: any) => any;
}

当我注释函数时 ModuleFactory(environment){..} 仅在第一个有效时，第二个 return 打字稿错误

TS2693: "'ModuleFactory' only refers to a type, but is being used as a value here.",

如果你指出应该用第二个选项注释的 TS“东西”，我会理解其中的区别。

Answer 1

相当于第一个文件的 Lambda 是

declare module '@my/customs'{
     type ModuleFactoryFn = (environment: any) => any;

     export const ModuleFactory: ModuleFactoryFn;
}

typescript declare: what is the difference between `export function` and `export type .. lambda`?
